Chelsea manager Jose Mourinho claims the club will only move for Marseille striker Didier Drogba if Hernan Crespo opts to move on.

The Blues have been heavily linked with Drogba but Mourinho insists he may already have all the strikers he needs if Argentinian forward Crespo is in the right frame of mind to continue at Stamford Bridge.

The Portuguese coach was unimpressed by Crespo's late arrival for pre-season training but after talking to the player is now waiting to hear his future plans before trying to sign Drogba.

"We have to decide in the next few days, and I mean we, we as a club, Hernan, Hernan's family, what is going to happen with Hernan," Mourinho said.

"And if the decision is for Hernan to go looking for a new club, we have an open space.

"What I can say is that Didier Drogba is one of the best strikers in Europe and since I played against him and I start looking at him through different eyes, I feel he needs a better club and a better league to show what he really is.

"So he can become a good option if in the next days we decide about Hernan."

Mourinho feels he needs three out-and-out strikers, with another target Mateja Kezman plus Crespo or Drogba being two of them.

The third is Eidur Gudjohnsen, who Mourinho says he has been pleasantly surprised by in the first few days of training.

"At the moment, pure strikers, we have one that for me day after day I am thinking is better than what I thought. Eidur. And he's improving a lot, and I believe that the specificity of our work can improve him a lot. So I'm really happy with that," he added.

Midfielder Scott Parker is looking to firmly establish himself at Chelsea after joining the club in a £10m move from Charlton in January.

"This season I've got the chance to push on and establish myself as a Chelsea player.

"When I came to Chelsea I came here because I wanted to be a better player, learn off the top players, the international players, people like Frank Lampard who's done so well," he said.
